Restoring a '78' GL1000

Postby D2D » Wed Apr 13, 2011 4:08 pm



Hello everyone, nice place ya got here. Hope you don't mind me pulling up a chair and asking a couple of questions. I'm not new to bikes; but am new to this Goldwing and could use a couple of pointers.

First a little history; I picked up this '78' at a yard sale a week ago, it is the naked GL1000 and is all there. It has sat, so I was told, for 2-years under a cover outdoors and before that it was garaged and running. A bit dirty and rusty in spots; but overall not in bad shape and only has 7,235 miles on it. The tank was half full of whatever you call gas that has seen it's last days and smelled worse than old sneakers. Thank God the previous owner had the sense to disconnect the fuel line at the tank and hopefully not allow any of that stuff to get into the carbs. I pulled the line off at the fuel pump and took the cover off for a look-see and it was clean, no visible rust or varnish. I opened the screws on the bottom of the carb bowls and nothing came out; but of course that doesn't mean they aren't full of trash or worse. All the electrical works, so I am already ahead of the game in that dept. I have filled the tank with vinegar and letting it sit for a couple of days and cross my fingers the pickup tube and/or screens aren't clogged solid or I'll be looking for a replacement. I could use a bit of help from you experienced owners with the following questions.

I have checked through the how tos here and didn't see any info on pulling the carbs. Is there a specific sequence to follow ? I was told it is a real son-of-a-gun to pull them off.

If I have to pull it, gas tank comes out through the rear, correct?

My other issue is a frozen front brake caliper anyone had to deal with this issue before?

Thanks for looking and any help you can give to this first time GW owner.

There are how to's on this site about everything you ask about.Tank comes out after the swing arm,rebuild the caliper and master cylinders,yes all of them.Carbs come out the left side and can be difficult the first time.The second time takes 35 minutes.Replace the timing belts(a must).

D2D: Welcome to the forum. Here is the carb removal procedure for the gl1000 and more from Pistol-Pete.
http://www.oldwings.com/services.html

Gas tank removal: Remove the right side cover. Remove rear master cylinder bolts and brake pedal rod eye pin. Move the master cylinder away from the fuel tank do not disconnect the brake line. Remove petcock. Remove seat. Disconnect tail light wires. Remove grab bar. Remove rear fenders. Remove shocks. Remove wheel. Remove fuel tank sender cap and sender unit. Remove battery box. You may have to loosen the false tank frame and raise it to get the tank out of the frame.

Seems everything you need to do on these old Wings is that way. ;)

We're in the same boat. I fixing up my "new" 78 as well. Although I got mine from a used car dealer. Mine came as a bagger with a vetter fairing and over 35k miles. Here's to fun and adventure :D

Hi there Optimurphprime , looks like I'm in good company here and will now have someone else to tease for answers to my questions.

Here's an update on my progress.
Replaced the gas tank: Several methods I tried to clean it revealed clogged screens and a rotted out line. I was gonna grab a reconditioned one but checking on my local Craigslist found one 2 hours away that was nearly spotless for a measly $35 and it included the sending unit, cap and drain plug.
The fellow that sold me this tank had stripped down a '78' he owned and had several parts still stored in a footlocker in his garage. I also bought the air box complete with a new filter still in the packaging from him for $5 and a rear tire ( Continental 130 x 90 x 17 in nearly new condition, mounted on a spotless wheel for another $25, that he had hanging on the wall.
Replaced the fuel pump: Inspection found a small tear in the diaphragm and thought it best to try to find another. I Picked up a used one from a dealer I had purchased parts for my CX500 from for $30 and it's on it's way.
I went over all of the wiring, disconnected and cleaned every connection and put it all back together and gave it all a shot of silicone spay to keep the moisture out.
I sprayed some gas directly into the carbs from the open air box and got her to fire up for a few seconds just to make sure the plugs were getting spark.
I am in the process of finding some mufflers for her as the old ones had rotted through and were unrepairable.
While searching for parts and waiting for responses to my emails I have been cleaning and polishing.
Once I get the new fuel pump and mufflers on I'll post another update.

Add another beginner to the list. Got a 79 with what he claims dirty carbs. Tried to turn it over, nothing. Pulled of a saddle, seat, and side covers and discovered a fusable link bypassed. So I have to do some wire to start. I hope to learn from other bikers experience. Thanks.

@D2D - That looks like a nice bike. I just finished collecting parts for my new '79 and started pulling the carb. The '79 must be a little different than other year models because the air box doesn't pull out the top and I can't seem to get to the Air Cutoff screws which, I believe, is the only thing keeping these from sliding out.

Removal instructions are here: http://www.randakks.com/Carb%20Removal.htm

Good luck and keep us posted, I'll be watching for tips.

Hey, glad to see a '79 being saved. Once to get her to crank, be sure to check for spark before doing fuel system work.

Did that and got her to fire up. Could only keep it running for about 15 seconds or so. The gas was pooring in. So I ordered a carb kit, started to disassemble the carb and found the floats were frozen stiff. Rebuilt it, put her on, fired right up. Bought some gauges, sync'd the carbs with in 1/2lb. Thanks to a great advise somewhere on this site. I could get 1-2-4 to sync and not 3. To find out I needed more adjustment on 1, problem fixed. Replaced the belts, polishing the covers (big job), then valve covers and I will check them before I put all the covers back on. All these sites have been great on helping fix up the bike. Thanks to all the excellent tips.

My one tip, I used a torch tip cleaner to clean float hindge holes. Worked great.
